  • To find the area, we divide the shape into two parts at approximately the middle line. The top shape is a trapezoid of base length 7 feet and height 6 feet, while the bottom shape is a parallelogram with one side equal to 4 feet.

    Area of trapezoid = (7 + 4)/2 x 6
    Area of trapezoid = 33 sq ft

    Area of parallelogram = 4 x 4
    Area of parallelogram = 16 sq ft

    Total area = 49 sq ft

    Cost = 2.25 x 49
    Cost = $110.25
  • Answer:

    110.25

    Step-by-step explanation:

    To find the area, we at a divide the shape into two parts approximately the middle line. The top shape is a trapezoid of base length 7 feet and height 6 feet, while the bottom shape is a parallelogram with one side equal to 4 feet.

    Area of trapezoid = (7 + 4)/2 x 6

    Area of trapezoid = 33 sq ft

    Area of parallelogram = 4 x 4

    Area of parallelogram = 16 sq ft

    Total area = 49 sq ft

    Cost = 2.25 x 49

    Cost = $110.25
